Re: what is "Stealth Address Data" in transactions?!

i was looking at the transaction in a recently mined block that i came across "Stealth Address Data"
her is the transaction:
https://blockchain.info/tx/fb225c26d4076de62c99bbdb611924c4e457f7df7ec6fa98ee092ea0a870d1be
what is it?

there are more of this on the block!

Don't hold me on this but I believe it's a DarkWallet address.
I could be wrong though.
Maybe someone else can shed some light here.
